Úll is a conference for iOS / OSX / mobile web developers and designers. The three day event will include workshops, keynotes, talks and in-depth presentations on all the aspects of building, designing and marketing your apps.

The conference takes place April 27–29, 2012 and there are still tickets available — I’m looking at making the trip myself. They also have a great list of speakers that includes Michael Lopp, Horace Dediu, Matt Gemmell, and others.

The conference organizers have kindly offered The Loop readers a €50 discount. You can claim the discount here.
